To get optimal performance, make sure your queues stay as short as possible all the time.
Longer queues impose more processing overhead.
We recommend that queues should always stay around 0 for optimal performance.

Em cenários com muitos consumers e publishers, o ideal é centralizar a criação de exchanges e queues, removendo essa permissão deles e fazendo essa gestão por uma equipe de admin.

Para garantir a entrega das mensagens o correto é usar consumer ack, broker ack e durable queue com persistent messages.
Pode-se utilizar quorum queues dependendo do cenário.

Remote debugging allows us to execute and capture code in remote devices, providing a way to inspect HTML, CSS and JavaScript and make live changes. In terms of mobile, this means a way for us to communicate with mobile devices so we can debug code on them directly rather than just relying on emulators.

The landscape for remote debugging your apps on mobile is quite strong at the moment.

Chrome for Android supports remote debugging via USB and allows you to debug using the Chrome Developer Tools. (See: https://developers.google.com/chrome/mobile/docs/debugging and Chrome for Android Remote Debugging for +Boris Smus's video walkthrough)

Opera has had support for remote debugging since 2008 and Dragonfly can remotely connect to Opera Mobile. (Tut: http://www.codegeek.net/blog/2012/mobile-debugging-with-opera-dragonfly/)

tmux cheat sheet

(C-x means ctrl+x, M-x means alt+x)

Prefix key

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

remap prefix to Control + a
